I was going to give myself 0.5 for this but decided not to. I don't wear an ipod very much anymore because i'm always training with someone. When I did wear one, I couldn't switch it on FIRST because foam rolling is the first thing I do when I get to the gym and the Ipod get's in the way.

I suspect either Mike or someone like him wrote this i.e. someone who doesn't train in commercial gyms. I never found an Ipod particularly comfortable but there's 2 good reasons to have one when you train,

1. The music in commercial gyms is always crap.
2. In a commercial gym, and Ipod is like a 'leave me a lone, don't speak to me' signal. It helps you just get through things which isn't very 'geeky' at all.

Yes - I would of said the weakest part for most/all people is the top. Getting the chin over the bar and/or chest to bar. I know Mike Boyle prefers the chest to touch the bar so he probably means this. However, most that cheat with pull ups won't go all the way up or down, and do reps in the middle portion only, as Jungledoc said.

Hmm I hadn't considered that half. :) Agreed that the hardest peak is about 3 inches from getting chin above hands. However I think the second-hardest peak of effort is when the upper arm is roughly parallel to the ground. But the parallel point mainly just feels like biceps, whereas the point close to the chin feel more holistic with lats.
